618 ON SOME PAUROPODA FROM N. S. WALES, 



pendages, commencing with the antennae, which are hauled down by 

 a vigorous curling of the corresponding first leg about them, and 

 drawn rapidly across the mouth; and proceeding on to each pair 

 of legs in turn, the limbs being systematically washed from coxa 

 to tarsus. The attitude assumed, in cleaning the extended hinder 

 limbs, is amusingly reminiscent of the same process in the domestic 

 cat. 



Tlie general form is robust, widest and highest at the fifth dorsal 

 shield, and tapering gradually forwards and abruptly backwards. 

 The whole cuticle is minutely pilose, the pubescence being a little 

 stronger on the head, dorsal shields, and posterior legs. The an- 

 terior has the two basal joints short and subequal, the third about 

 twice the length, the fourth longest, and swollen distally. The 

 lower ramus is about two-thirds as long as the upper, and but little 

 wider. Its anterior flagellum is less than half the posterior, and is 

 borne on the truncated anterior corner. The basal unringed por- 

 tion of the flagella is short. The globulus is small, and almost ses- 

 sile. The upper ramus has its flagellum about one-fifth longer than 

 the posterior flagellum. On the dorsal surface of the head, the 

 "eyes" are widely separate, their inner margins being on a level 

 with the bases of the fourth antennal segments. * There are three 

 cylindrical hairs on either side, behind "eye"; a fourth hair of 

 similar character projecting laterally in front of these. Mid-dor- 

 sally, in front of posterior margin, a pair of slightly club-shaped 

 hairs ; in front of these a row of four, similar ; in front of these, a 

 pair, similar, with a pair curved-cylindrical, laterally ; before these, 

 a row of six, then a median hair projecting forwards between bases 

 of antennge, all definitely club-shaped. The first dorsal shield is 

 hardly wider than the head, the foUowmg shields gradually widen- 

 ing to the fifth; sixth narrower, with the rounded anal segment pro- 

 jecting beneath it. The shields are almost straight along the an- 

 terior border, but broadly rounded behind. The first bears a 

 row of four hairs along the anterior border, the outer pair being 

 cylindrical, not clavate; and a row of four clavate hairs along 

 the posterior border. The second has a row of four clavate hairs 

 in front of the middle, and a similar row close to the posterior
